Hi all, I am trying to get bootstrap resampled estimates of covariates in a Cox model using cph (Design library).
Using the following I get the error: > ddist2.abr <- datadist(data2.abr) > options(datadist='ddist2.abr') > cph1.abr <- cph(Surv(strt3.abr,loc3.abr)~cov.a.abr+cov.b.abr, data=data2.abr, x=T, y=T) > boot.cph1 <- bootcov(cph1.abr, B=100, coef.reps=TRUE, pr=T) 1 Error in oosl(f, matxv(X, cof), Y) : not implemented for cph models > Removing coef.reps argument works fine, but I really need the coefficients if at all possible. I cant find anything in the help files suggesting that I cant use coef.reps in a cph model. Any help appreciated.
